That is the opposite of the US model, and it moves the risk. - Author: Milos Djukanovic - Tags: Fundamentals, Stablecoins A euro stablecoin and a dollar stablecoin look identical and are backed by structurally different things. US rules push reserves toward short-dated government debt. EU rules push them toward bank deposits. MiCA requires e-money token issuers to hold at least 30% of reserves as deposits in EU credit institutions, rising to 60% for tokens designated as significant. That is not a preference an issuer can optimise away; it is a floor written into the regulation. This guide explains what the rule requires, why the EU chose it, and the consequence almost nobody states: the requirement mandates precisely the exposure that broke USDC's peg in 2023. > Hold a dollar stablecoin and you are indirectly a holder of US government debt. Hold a euro stablecoin and you are indirectly a bank depositor. Same product, different creditor. ### Key Takeaways - **MiCA sets a deposit floor.** At least 30% in EU credit institutions, 60% for significant tokens. - **The US model runs the other way.** Reserves concentrate in short-dated Treasuries and repo. - **The exposure differs, not the quality.** Bank credit risk replaces sovereign duration risk. - **This is the SVB exposure by design.** The 2023 depeg came from stranded bank deposits. - **The market is small.** Euro stablecoins are roughly 0.24% of global supply. --- ## What the Rule Requires Two MiCA provisions govern euro stablecoin reserves, and they operate together. Article 38 requires reserves to be held in highly liquid, low-risk investments and sets a 30% floor for deposits at EU-licensed credit institutions for non-significant e-money tokens, rising to 60% for those designated significant. Article 36 requires monthly disclosure of reserve composition. The remainder can sit in other qualifying liquid assets, so a euro stablecoin is not backed entirely by deposits. But a substantial and legally mandated share is, and for the largest tokens the majority is. --- ## How That Compares to the US Model Setting the two frameworks side by side shows the divergence clearly. | | MiCA (EU) | GENIUS Act (US) | | ---------------------- | ------------------------------ | ------------------------------------- | | Bank deposits | Mandatory floor, 30% or 60% | Permitted, not required | | Government debt | Permitted within liquid assets | Central: Treasuries up to 93 days | | Repo agreements | Within qualifying assets | Explicitly eligible | | Government money funds | Within qualifying assets | Explicitly eligible | | Disclosure cadence | Monthly, Article 36 | Monthly, PCAOB-registered attestation | | Primary counterparty | European banks | US Treasury | Both frameworks demand full backing in liquid, low-risk assets, so neither is loose. What differs is where the risk sits, a distinction our guide to [**how stablecoins are backed**](https://stablecoininsider.org/how-are-stablecoins-backed-reserves-attestations-audits/) traces across issuers. [![How Are Stablecoins Backed? Reserves, Attestations & Audits](https://storage.ghost.io/c/73/6a/736af0e4-2274-4543-a329-2952b2b52abc/content/images/2026/08/Screenshot-2026-08-28-at-22.08.19.png)](https://stablecoininsider.org/how-are-stablecoins-backed-reserves-attestations-audits/) --- ## Why the EU Chose Deposits The reasoning is monetary rather than prudential, and it makes sense once stated. A large pool of euros held in non-EU assets would remove that money from the European banking system, which funds European lending. Requiring reserves to sit in EU credit institutions keeps euro stablecoin growth inside the deposit base rather than diverting it abroad. The contrast with the US is instructive. American rules channel stablecoin reserves toward Treasury bills, making issuers structural buyers of government debt, a dynamic our guide to [**stablecoins and the US Treasury market**](https://stablecoininsider.org/stablecoins-and-the-us-treasury-market/) examines. European rules channel them toward bank funding instead. [![How Do Stablecoins Affect the US Treasury Market?](https://storage.ghost.io/c/73/6a/736af0e4-2274-4543-a329-2952b2b52abc/content/images/2026/08/Screenshot-2026-08-28-at-22.08.42.png)](https://stablecoininsider.org/stablecoins-and-the-us-treasury-market/) Each jurisdiction directed the money where it wanted it. Neither decision was primarily about holder safety. --- ## The Consequence Nobody States Here is where the rule becomes uncomfortable, and it follows directly from what happened three years ago. In March 2023, USDC fell to roughly $0.87 because $3.3 billion of its reserves, about 8% of backing, were stranded at Silicon Valley Bank when it failed. The token was fully reserved throughout. The problem was that a portion of those reserves sat in a bank that stopped functioning over a weekend. Circle's response was to move most of the cash leg into a government money market fund and cap exposure to any single bank. Under MiCA, a euro stablecoin issuer cannot make that move, because a minimum share of reserves must remain in EU credit institutions. So the regulation mandates the category of exposure that produced the most significant depeg of a major fiat-backed stablecoin, a mechanism our guide to [**what a stablecoin depeg is**](https://stablecoininsider.org/what-is-a-stablecoin-depeg/) sets out in detail. [![What Is a Stablecoin Depeg? (2026)](https://storage.ghost.io/c/73/6a/736af0e4-2274-4543-a329-2952b2b52abc/content/images/2026/08/Screenshot-2026-08-28-at-22.09.11.png)](https://stablecoininsider.org/what-is-a-stablecoin-depeg/) --- ## What Cuts the Other Way The argument above is real and it is not the whole picture, so three qualifications belong alongside it. European bank supervision is stringent, and the deposit requirement spreads across EU credit institutions rather than concentrating in one. SVB was a mid-sized US regional bank with an unusual deposit base, not a systemically supervised European institution. Deposit guarantee schemes exist across the EU, though their design limits their relevance here. They protect up to €100,000 per depositor per institution, which is meaningful for a retail account and immaterial against a reserve pool measured in hundreds of millions. And Treasury exposure is not risk-free either. It substitutes duration and liquidity risk for credit risk rather than removing risk, which is why the honest framing is a different exposure rather than a worse one. --- ## The Market These Rules Govern Scale matters for interpreting all of this, because the euro segment remains very small. A token-by-token screen in late August 2026 identified roughly €632 million of redeemable and economically active euro stablecoins, against global stablecoin capitalisation near $304 billion. That is about 0.24% of the market, with close to 98% of global value dollar-denominated. Concentration is high within that segment. Circle's EURC held roughly 62% of screened euro supply and Société Générale's EURCV about 23%, so two issuers account for around 85% of the total. The practical implication is that MiCA's reserve architecture currently governs a market small enough that its structural properties have never been tested under stress. --- ## What to Check Before Holding One Three questions extract what matters from any euro stablecoin's disclosures. **What share sits in deposits, and at how many banks?** The floor is 30% or 60% depending on designation, and issuers may hold more. Concentration across few institutions is the specific risk the floor creates. **Which institutions hold them?** Article 36 requires monthly composition disclosure, and the level of detail varies considerably between issuers. **Is the token designated significant?** That designation raises the deposit floor from 30% to 60%, so growth in a token's size mechanically increases its bank exposure rather than reducing it. --- ## Conclusion What actually backs a euro stablecoin? Liquid low-risk assets under MiCA, with a mandated minimum of 30% in EU credit institution deposits, rising to 60% for significant tokens. That is a genuinely different structure from the US model, where reserves concentrate in short-dated government debt and bank deposits are permitted rather than required. A euro stablecoin holder's ultimate counterparty is the European banking system; a dollar stablecoin holder's is the US Treasury. Neither arrangement is safer in general, and each carries the risk the other avoids. What is worth knowing is that the European framework requires the specific exposure that caused the largest depeg in the regulated stablecoin era, and that the market it governs is still small enough that nobody has found out what that means under pressure. ***Read Next:*** - [**How Are Stablecoins Backed?

What backs a euro stablecoin under MiCA? Highly liquid, low-risk assets, with Article 38 requiring at least 30% of reserves to be held as deposits at EU-licensed credit institutions for non-significant e-money tokens, rising to 60% for tokens designated significant. Article 36 requires monthly disclosure of reserve composition. ### 2\. How is that different from a dollar stablecoin? The US GENIUS Act channels reserves toward short-dated government debt, covering Treasury bills up to 93 days, repo agreements, government money market funds, and demand deposits, with bank deposits permitted rather than required. The result is that a dollar stablecoin holder's ultimate counterparty is the US Treasury while a euro holder's is the European banking system. ### 3\. Why does the EU require bank deposits? Because reserves held in non-EU assets would remove euros from the European banking system that funds European lending. The requirement keeps euro stablecoin growth inside the deposit base, which is a monetary policy consideration rather than a holder protection measure. ### 4\. Does the deposit requirement make euro stablecoins riskier? It creates a different exposure rather than a strictly worse one. Bank deposits carry credit risk, and USDC's 2023 depeg came from $3.3 billion stranded at a failed bank, but Treasury exposure substitutes duration and liquidity risk rather than eliminating risk, and EU bank supervision is stringent. ### 5\. Are euro stablecoin deposits covered by deposit insurance? EU deposit guarantee schemes protect up to €100,000 per depositor per institution, which is designed for retail accounts and is immaterial against reserve pools measured in hundreds of millions. Holders of the token itself have a redemption claim on the issuer rather than an insured deposit. --- ***Disclaimer:*** This content is provided for informational and educational purposes only and does not constitute financial, investment, legal, or tax advice; no material herein should be interpreted as a recommendation, endorsement, or solicitation to buy or sell any financial instrument, and readers should conduct their own independent research or consult a qualified professional.
